I've had PhotoVCarve for quite a while... just never used it. I was looking at the features of it, and see where it's supposed to do 3D Grayscale Machining with a ball bit. How do I get that to work? I looked at the videos and didn't see anything about it. Am I missing an update, 'cause I don't see anything in the software that says anything about it.

That PDF is great but the picture I am using is not in gray scale. So are you saying that converting the picture to greyscale will do the trick? So then my next question is, How do I convet the picture to greyscale?
